Convert dpx to YUV

[sprito]

Hello!
This is my very first topic! I am new here and I should say that I am delighted with ImageMagick ( even knowing very little about it [but that's gonna change soon ]) .
Well I am facing a problem with a simple conversion of a dpx file into a YUV444 file.
the point is that the output of :
convert frame.dpx frame.yuv
is YUV420.
I would appreciate to know if there is a command line option that solves this ( though I've read the entire (convert -help >).txt)
And also I would like to know if there is a possibility of conversion of a set of dpx files into a single yuv file.

Thanks.

I've also searched the forum and found this: Convert DPX YUV 4:2:2 to TGA RGB
but it didn't help too much.

ImageMagick supports YUV CCIR 601 4:1:1 or 4:2:2. ImageMagick is open source so you are welcome to extend the YUV writer found in the source distribution as coders/yuv.c.

all right!
I am going to look the code and then I will post my advance.
thanks!
